1) $\frac{1}{2} + 6\frac{3}{7} = \frac{1}{2} + \frac{45}{7} = \frac{7}{14} + \frac{90}{14} = \frac{97}{14} = 6\frac{13}{14}$

НОЗ: 14.

2) 6 + $4\frac{9}{11} = \frac{6}{1} + \frac{53}{11} = \frac{66}{11} + \frac{53}{11} = \frac{119}{11} = 10\frac{9}{11}$

3) $\frac{3}{9} + 1\frac{8}{15} = \frac{3}{9} + \frac{23}{15} = \frac{15}{45} + \frac{69}{45} = \frac{84}{45} = 1\frac{39}{45}$

НОЗ: 45.

4) $\frac{1}{14} + 9\frac{3}{7} = \frac{1}{14} + \frac{66}{7} = \frac{1}{14} + \frac{132}{14} = \frac{133}{14} = 9,5$

НОЗ: 14.

5) $7\frac{1}{12} + 6 = \frac{85}{12} + \frac{6}{1} = \frac{85}{12} + \frac{72}{12} = \frac{157}{12} = 13\frac{1}{12}$

НОЗ: 12.

6) $\frac{5}{7} + 3\frac{1}{4} = \frac{5}{7} + \frac{13}{4} = \frac{20}{28} + \frac{91}{28} = \frac{111}{28} = 3\frac{27}{28}$

НОЗ: 28.

1) $\frac{7}{1} - \frac{21}{4} = \frac{28}{4} - \frac{7}{4} = \frac{21}{4} = 5\frac{1}{4} = 5,25$

НОЗ: 4.

2) $\frac{6}{1} - \frac{17}{3} = \frac{18}{3} - \frac{17}{3} = \frac{1}{3}$

НОЗ: 3.

3) $\frac{12}{1} - \frac{75}{8} = \frac{96}{8} - \frac{75}{8} = \frac{21}{8} = 2\frac{5}{8} = 2,625$

НОЗ: 8.

4) $\frac{11}{1} - \frac{20}{3} = \frac{33}{3} - \frac{20}{3} = \frac{13}{3} = 4\frac{1}{3}$

НОЗ: 3.

5) $\frac{8}{1} - \frac{23}{7} = \frac{56}{7} - \frac{23}{7} = \frac{33}{7} = 4\frac{5}{7}$

НОЗ: 7.

6) $\frac{71}{13} - \frac{2}{1} = \frac{71}{13} - \frac{26}{13} = \frac{45}{13} = 3\frac{6}{13}$

НОЗ: 13.

7) $\frac{93}{10} - \frac{4}{1} = \frac{93}{10} - \frac{40}{10} = \frac{53}{10} = 5,3$

НОЗ: 10.

8) $\frac{31}{14} - \frac{14}{14} = \frac{17}{14} = 1\frac{3}{14}$

Целая превращается в 14/14.
